2023 Jeep Wrangler Fuse Box Diagram & Amperage

Quick answer

The 2023 Jeep Wrangler typically has two main fuse box locations: under the hood (Power Distribution Center) and inside the cabin on the passenger side kick panel. Some models, especially those with specialized features or aftermarket installations, might have auxiliary fuse holders, but these two are the primary factory fuse boxes.

Under-Hood Fuse Box (Power Distribution Center)

The Power Distribution Center (PDC) is located in the engine compartment on the passenger side. It contains high-current fuses and relays for critical engine functions, lighting, and other major electrical systems. Always consult the fuse legend on the underside of the PDC cover for the exact layout and amperage specific to your vehicle's trim and options, as configurations can vary.

Here’s a common configuration for the 2023 Jeep Wrangler PDC. Note that numbering and specific circuits can vary by trim level and installed options.

Relay Locations (Under-Hood PDC):

• R1: Starter Relay
• R2: Fuel Pump Relay
• R3: Run/Accessory Relay
• R4: ECM/PCM Relay
• R5: Radiator Fan Relay
• R6: A/C Clutch Relay
• R7: Horn Relay
• R8: Wiper Motor Relay

Cabin Fuse Box (Passenger Side Kick Panel)

The cabin fuse box is located on the passenger side of the vehicle, behind the kick panel. This fuse box primarily protects interior electrical components, infotainment, power outlets, and other accessory circuits. To access it, you'll typically need to remove the kick panel cover. Always verify the fuse legend printed on the inside of the cover for your specific vehicle.

Here’s a common configuration for the 2023 Jeep Wrangler cabin fuse box. Keep in mind that fuse locations and protected circuits can vary with trim levels and optional equipment.

How to test a fuse

Testing a fuse is a straightforward process and a good first step when diagnosing an electrical issue. Here’s how you can do it:

1. Safety First: Ensure the vehicle's ignition is off and disconnect the battery's negative terminal if you're working on high-current fuses or relays, to prevent accidental shorts.
2. Locate the Fuse: Refer to the appropriate fuse box diagram (under-hood or cabin) to identify the fuse for the circuit you are troubleshooting.
3. Visual Inspection: Most modern fuses have a small wire visible through a clear plastic body. If this wire is broken or melted, the fuse is blown and needs replacement.
4. Use a Test Light or Multimeter:
   • Test Light: With the ignition on (and the component that uses the fuse turned on, if relevant, such as headlights), touch the tip of the test light to the two small metal test points on the top of the fuse. If the test light illuminates on both sides, the fuse is good. If it only illuminates on one side or not at all, the fuse is blown.
   • Multimeter: Set your multimeter to the continuity or ohms setting. Remove the fuse from its slot. Touch the multimeter probes to each metal blade of the fuse. A good fuse will show very low resistance (close to zero ohms) or indicate continuity (a beep, if your multimeter has an audible continuity feature).
5. Replace if Blown: If the fuse is blown, replace it with a new fuse of the exact same amperage rating and physical size. Using a fuse with a higher amperage rating can lead to serious electrical damage or fire.

Common Blown Fuses on this vehicle

While any fuse can potentially blow, certain circuits are more prone to issues due to the nature of their use or the components they protect. For the 2023 Jeep Wrangler, common fuses that might blow include:

• Cigar Lighter/12V Power Outlets (F31, F32): These fuses often blow when aftermarket accessories draw too much power, or if a faulty device is plugged in. Always check these first if your phone charger or other 12V accessories stop working.
• Radio/Infotainment (F30): Issues with the radio, Uconnect system, or other infotainment components can sometimes be traced back to a blown fuse, especially after a power surge or if an aftermarket stereo was installed incorrectly.
• Headlights/Fog Lights (F08, F09, F10, F11, F20): While less common with modern LED systems, a sudden failure of one or both headlights or fog lights can sometimes be a fuse issue, though more often it’s the bulb or wiring itself.
• Blower Motor (F04): If your cabin fan stops working entirely, the blower motor fuse is a good place to start your investigation. A failing blower motor can draw excessive current and blow its fuse.
• Trailer Tow Connector (F15): If you experience issues with trailer lights or trailer braking, check this fuse. Improper wiring on a trailer or an overload can cause it to blow.

What to check first:

When a component or system stops working, first identify which fuse protects that specific circuit using the fuse box diagrams above and your vehicle's fuse box lid legend. Then, perform a visual inspection of that fuse. If it appears intact, use a fuse tester or multimeter to confirm continuity. If the fuse is good, the issue lies elsewhere in the circuit or with the component itself.
